VIP monsters have become woefully lacking since shortly after they were all released.
1)Monsterlab came out and made VIP weak right away unless you spent loads of $$$ to rank
2)Two breed events since then for VIP as a solution to problem 1 doesn't cut it
3)Nemesis are the same price and magnitudes better, they even have the bulwark trait.
4)New monsters coming out have beefed up traits and very powerful moves, and they are only 249 gems to get. Many outclass VIP's especially for the price.
I think they should create a 4th tier of moves for ranked VIP's to bring them up to date and make them worth buying, upgrading.
